MARQUIS D. HANLON, OF WILKINSBURG, PENNSYLVANIA, ASSIGNOR TO THE UNION SWITCH AND SIGNAL COMPANY, OF SVVISSVALE, PENN- SYLVANIA, A CORPORATION OF PENNSYLVANIA.

APPARATUS FOR MOVING SWITCH-RAILS.

SPECIFICATION forming part of Letters Patent No. 791,025, dated May 30, 1905 Application filed February 17, 1905. Serial No. 246,046.

T (1 whom it may concern:

Be it known that I, IVIARQUIS D. I-IANLoN, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Moving Switch-Rails, of which the following is a specification.

My invention relates to apparatus for mov- 1 ing, shifting, or operating railway-switches and in which the motive power may be either electric or pneumatic.

I will describe a railway-switch-operating apparatus embodying my invention and then I 5 point out the novel features thereof in claims. In the accompanying drawings, Figure 1 is a top plan View of a railway-sWitch-operating apparatus embodying my invention and showing it connected to two switches to be operated independently by electric motors. Figs. 2, 3, and 4 are top plan views of a floating lever and its support, showing in full and dotted lines positions the lever will assume in operating the detector-bars. Fig. 5 is a perspective view of the lever-guide. Figs. 6 and 8 are vertical sections thereof, taken at right angles to each other. Fig. 7 is a top plan view showing switch-operating apparatus embod ying my invention and operated by a pneu- 3 matic motor. Fig. 9 is a bottom plan view, on enlarged scale, of the lever and cam-plate of Fig. 7 for operating the switch-rails.

Referring now to Figs. 1 and 7 A A and A A indicate oppositely facing pairs of switch-rails, adapted to cooperate with the rails A and A in the usual manner. According to my present invention there is an operating apparatus for moving and locking each pair of switch-rails independently, and there 4 is one set of detector-bars for both switches, which will be operated when either one or both of the switches is operated. As shown in Fig. 1, this operating apparatus is substantially the same as that described in my prior application, upon which Patent No. 762,997, dated June 21, 1904:, was granted, and comprises an electric motor B, an electric clutch C, a speed-reducing gear D, and a camcylinder E, there being a separate operating apparatus for each pair of switch-rails. The cam cylinders E have two grooves e e, of which the latter operates the switch-rails through the medium of a bell-crank lever c and rod 6, connected to the bridle-rod 6 joined to the switch-rails. The locking means for 5 5 the switch-rail is indicated generally by F and is operated by the cam-groove 0 through the medium of the lever f and rod f. The locking-bar connected to the switch-rails is indicated by The operation of all the parts of the operating apparatus so far described is the same as set forth in the said patent and need not be specifically set forth herein.

G and G indicate detectonbars adapted to protect both switches and to be operated simultaneously no matter which of the pairs of switch-rails is moved or if both pairs are moved together. It is unnecessary to describe in detail how these detector-bars are mounted, for this, as well as the manner in 7 which they move, is well known in the art. As shown in the drawings, they are connected by the rods 9 and g to arms 9 on arock-shaft 9 so that when the shaft 9 is rocked in one direction both detector-bars will be lifted q 5 higher than the rails A A providing there is nothing to prevent their having this movement, and when the shaft is rocked in the other direction the bars will be returned to normal position, and I therefore provide some means for rocking the shaft 9 when either or both pairs of switch-rails moves.

In the present instance I have shown a floating lever H, supported to move laterally in aguide I. This guide is shown more par- 5 ticularly in Figs. 5, 6, and 8, and, as shown, consists of two substantially U-shaped body portions t' 2', each having two arms 2" extending tangentially from each side. The two body portions are arranged so that their side 9 edges oppose each other, and bosses i are formed on the arms a" to keep the side edges of the two body portions apart, and thereby forming a slot or opening i between the two body portions through which the lever H extends and in which it may move laterally.

The arms of the upper part will be secured to those of the lower part in any suitable manner and the entire guide be secured to a suitable support by the feet 2'.

Referring now particularly to Figs. 6 and 8, it will be seen that a bolt 71, passes through the lever H within the guide and that the forked end 70 of a rod 70 straddles the lever H, and the. bolt 71 also passes through the forked end. The rod in" is thus pivotally connected to the lever H within the guide. Rollers h are also supported upon the bolt to en: gage ribs 71 on the inner surface of the guide, so that the lever H can move freely laterally, but not lengthwise, in the guide. The rod 76 extends through one end of the guide I and is connected to an arm 9 on the rock-shaft g One end of the lever H is connected to the lever f of one operating apparatus by a rod n and the other end to the lever f of the other apparatus by the rod 12.

Referring now to Figs. 7 and 9, B indicates a pneumatic motor with a reciprocating piston b. I have not deemed it necessary to illustrate this motor in detail nor its connections to the compressed-air reservoir or other source of supply, as these may be of any preferred type, and the mode of operation of these devices is well known. The piston is connected to a sliding bar 6, supported in suitable guides on a base-plate b and this bar may cooperate with the locking-bar f of the switch-rails to lock the latter, or it may operate a lock for this purpose. The bell-crank lever e for moving the switch-rails is operated by a sliding camplate 6 having a cam-slot 6*, the plate 5* being connected to and operated by this bar I). L is a cam-plate connected to the end of the bar 6' and supported to slide on a base-platel in a guide Z. This plate is provided with a cam groove or slot Z which operates the bellcrank lever Z, connected by a rod n or n to the floating lever H, it being understood .that each switch is provided with a duplicate set of the devices just described. The camslot Z is so formed that the lever Z will first be moved in one direction, then remain at rest, and finally be moved back to its original position during a complete endwise movement of the cam-plate L in either direction. The cam-groove e on the cylinder E will also operate the lever f in the same manner during a complete revolution of the cylinder in either direction, and therefore the operation of the floating lever H will be the same with either the electric or pneumatic apparatus.

The normal position of the lever H is shown in dotted lines in Figs. 2, 8, and 4. When the motor B for the switch-rails A A is operated, the lever H will first move to the position shown in full lines in Fig. 3, which will rock the shaft g and lift the detector-bars. The lever H will remain at rest while the switch-rails are being moved and will then return to its normal position, thereby again rocking the shaft 9 and lowering the detectorbars. The cam-slot I) in the cam-plate b is so formed that while the leverH is operating the lever a will not be moved. The same operation will occur in connection with the switchrails A A, Fig. 4 showing the position in full lines the lever H will assume to lift the detec-' tor-bars.

, In the event the switchrrails A A and A A are to be moved together and both motors are operating at the same time both ends of the lever H will be moved uniformly and the lever will assume the position shown in full lines in Fig. 2.

When the switch-rails AA only are to be moved, the lever H will have a fulcrum at its pivotal connection with the rod n, and when the rails A A only are to be moved the lever H will have a fulcrum at its pivotal connection with the rod 12/.
